HY-RIB AND METAL LATH 

Hy-Rib is a steel mesh stiffened by rigid ribs all manufactured from a single plate of steel. 
The Hy-Rib and Metal Lath line includes all depths and weights to exactly meet all require- 
ments (see following pages). The mesh of the Hy-Rib and Lath provides a perfect key for 
the plaster, and a rigid surface to work against. 

In concrete floors and roofs Hy-Rib (using 15 /i6" and W2") provides thorough reinforce- 
ment and eliminates forms. In sidings, partitions and ceilings Hy-Rib and Metal Lath 
permit wide spacing of supports, saving in channels and wiring. For arches and tanks 15 /i6" 
Hy-Rib is furnished curved by our factory (see page 7). 



Why You Should Use The Hy-Rib Line 

Eliminates all forms for concrete. Permits wide spacing of supports. 

Saves channels and wiring. Reduces weight of construction. 

Reinforces the concrete and plaster. Increases available floor space. 

Insures fireproofness and permanence. Saves time, labor and material. 



Where You Should Use Hy-Rib 

In all buildings, large or small — in roofs, floors, walls, sidings, partitions, 
ceilings and furring; in arched floors, culverts, conduits, sewers, silos and tanks. 

The Hy-Rib line lowers the cost of building because it eliminates forms, requires less 
labor, uses less materials and thus saves time in erection. Hy-Rib provides an enduring 
fireproof construction that is more economical than short-lived materials which burn, decay 
and depreciate. 

This book is arranged in sections starting with general descriptions of Hy-Rib products, 
followed by their general applications, such as roofs, floors, sidings, partitions, ceilings, etc. 
It is impossible within space limitations to show the hundreds of uses of Hy-Rib and Metal 
Lath products, nor to go into all the details of the general applications. We invite inquiries 
from prospective builders as to their particular requirements, and will gladly furnish without 
obligation detailed suggestions on the use of these products.

View shows if " Hy-Rib in Machine. 



The Hy-Rib Hand-Power Bender is readily operated by 
two men, so that Hy-Rib can be shipped in straight sheets 
and curved locally. This saves greatly in freight and 
crating charges, as curved Hy-Rib bulks largely and is 
much more expensive to pack and ship than straight sheets. 

The Hand-Power Bender curves Hy-Rib to any circular 
arc with radius between 13 inches and 20 feet.

FLOORS 

(For specifications and tables of carrying capacities of Hy-Rib floors, see Pages 15 to 17.) 

In concrete floors, Hy-Rib eliminates forms and rigidly reinforces the concrete. 
It simplifies construction, saves time, reduces costs and provides flat or arched 
floors with any type of beam. 

The use of Hy-Rib in floors is very simple. Lay the Hy-Rib over the supports with the 
mesh side down and pour on the concrete above. Only enough concrete flows through the 
mesh to secure a perfect clinch on the steel. The plaster is applied directly to the under 
surface. Hy-Rib provides in itself the forms and reinforcement for concrete, greatly reducing 
the cost of construction and saving time in erection. 

Hy-Rib is manufactured with a rib along each side of the sheet, making a perfect inter- 
locking splice when two sheets are joined. A similar interlocking splice is provided at the 
ends by allowing the two sheets to overlap. In this way absolute continuity of strength and 
reinforcement is provided throughout the entire floor surface. 

Practical builders know that forms are the most costly and troublesome part of concrete 
construction. By eliminating all forms, Hy-Rib greatly economizes construction, saving 
time, labor and money. 

Only the deeper types of Hy-Rib (IJH2" and 15 /i6") are ordinarily used in floors, but for 
short spans less than 3 feet other types may be used. 



ARCHED FLOORS 

All the expensive circular forms required in arched floor construction are eliminated by 
using Hy-Rib, which also provides a rigid, substantial reinforcement for the concrete. 

Our shops furnish 15 /ie " Hy-Rib bent to the exact curve, ready to set in place between 
the beams. All types of arched floors are provided (see pages 7 to 1 1), by this shop-curved 
Hy-Rib. Note that in many instances the Hy-Rib also furnishes the forms for the sides of 
the beams, as well as the forms and reinforcement for the floors. The shop bending does 
away with all special field labor and complicated circular forms.

tacked to the joists. Hy-Rib is placed and concrete poured to 
proper thickness. This concrete furnishes the necessary base 
for tile, terrazo or composition flooring.

Load of 1,400 lbs. per sq. ft. after Fire Test of 1700° for four hours. 



New York Fire Test on Hy-Rib Arch 

(Compiled from official report of Fire, Load and Water Test made upon 
cinder concrete floor arches at Columbia Fire Testing Station, New York. 
Test was conducted by Ira H, Woolson, R. M., in co-operation with City 
Building Bureaus.) 

Span of segmental arch, 8 feet; thickness at crown, 43^ 
inches; total depth at haunches, 15 inches. Concrete — 
Portland cement 1 part, sand 1 part, unsifted cinders 6 parts. 

The concrete floor arch reinforced with Hy-Rib was sub- 
jected to a continuous fire below the floor for four hours at an 
average temperature of 1700 degrees F., floor carrying at the 
same time a distributed load of 150 lbs. per square foot. At 
the end of the four hours the under side of floor while still red 
hot was subjected to an \yi inch stream of cold water for 
five minutes. Then the upper side of the floor was flooded 
and afterwards the stream was again applied on the under side 
for five minutes. 

After cooling, the arch was subjected to a load of 600 lbs. 
per square foot. Later a 6 ft. wide section was cut out of the 
floor arch and this section was loaded to 1400 lbs. per square 
foot. Under this severe load the deflection was only >4 inch. 

As a result of this test the Building Departments of Man- 
hattan and Brooklyn have approved the use of cinder concrete 
arches reinforced with Hy-Rib, 4 inches thick at the crown, for 
loads up to 350 lbs. per sq. ft. and span of 8 feet. 



Loads Carried by Arched Hy-Rib Floors 

Arched Concrete Floors are capable of carrying very heavy 
loads, as has been frequently demonstrated in actual tests. 
(See New York Fire Test, on this page.) Curved Hy-Rib 
is an ideal type of combined centering and reinforcement for 
arched floors. Expensive circular forms are eliminated and 
the Hy-Rib, curved in our own shops, is exceptionally eco- 
nomical in placing and handling. Curved Hy-Rib sheets have 
far greater stiffness as centering than straight sheets, thus 
permitting of a wider spacing of temporary supports. 

The theoretical design of arches assumes absolutely rigid 
abutments. The thrust per lineal foot may then be figured 
by' means of the following formula: 



T = 



1.5 WL 2 
R 



Where W=the load per square foot 

L=span in feet between supports, and 
R =rise of the arch in inches. 

The crown thickness may be determined by the following 
formula : 



C=- 



12S 



Where C = the crown thickness in inches 
T = the thrust per lineal foot, and 
S=the allowable fibre stress per sq. inch. 

In actual building construction, it is practically impossible 
to secure absolutely rigid abutments, unless tie rods are used, 
and the crown thickness must therefore be materially increased 
over the depth determined by the above formula. There is no 
question that an Arched Concrete Floor is capable of carrying 
considerably more load than a flat slab of the same thickness. 
For loads on flat slabs, see pages 16 and 17. 

Our engineers have had wide experience in the design 
of arched floors under varying conditions. We would be 
glad to submit our detailed suggestions on the design of 
arched floors to meet any particular condition.

ROOFS 

(For specifications and tables of carrying capacities of Hy-Rib roofs, see Pages 15 to 17.) 

Thin concrete roofs, light in weight, are built with Hy-Rib without the use of 
forms. The great saving in dead weight reduces the size and cost of purlins, roof 
trusses, columns and foundations. 

This thin slab also saves in concrete materials and in the labor of placing them. 

No forms are required with Hy-Rib concrete roofs. Consider the tremendous saving 
in false work, especially in industrial plants, where the roofs are often 20 to 50 feet above the 
ground. Hy-Rib provides a perfect fireproof construction at economical cost — easily and 
rapidly installed. 

The construction is very simple. Hy-Rib sheets are placed over purlins, concrete 
applied and under surface plastered. The simple scaffolding for the plasterers is readily 
hung from the steel trusses. 

The permanent nature of Hy-Rib concrete makes it far more economical than materials 
which rust, decay or depreciate. Hy-Rib concrete roofs entail no expense for maintenance. 
Owing to the insulating qualities of the concrete construction, a marked saving in cost of 
heating the building is effected. 

Only the deeper types of Hy-Rib (\}4" and 15 /w") are ordinarily used in roofs, but for 
short spans less than 3 feet other types may be used.

SPECIFICATIONS FOR HY-RIB FLOORS and ROOFS 



REINFORCING STEEL 

Provide Hy-Rib, Type , Gauge 

for all floors and roofs. 

Place all Hy-Rib sheets with the lath surface 
downward. Interlock all adjoining sheets of Hy- 
Rib at sides and ends. Sheets shall be securely 
fastened together every 24 inches along the sides 
and at every rib at the ends by wiring or by clinching 
of the lapped ribs with special punch. Where end 
splices occur between supports, splices in adjacent 
rows must be at least two feet apart. Allow a lap 
of 2 inches where splices occur over supports, 
otherwise 8 inches. 

Hy-Rib shall be rigidly attached to steel framing 
by means of clips or strong galvanized wire, and to 
wood framing by staples or nails. These attach- 
ments shall be located at the interlocking side 
splices at least every 12 inches for ff " Hy-Rib, and 
every 14 inches for \y 2 " Hy-Rib. 

Hy-Rib sheets shall be supported as required by 
centering tables, page 17, while concrete is being 
poured, and, if necessary, temporary supports shall 
be provided. 

No loads shall be placed on Hy-Rib before con- 
creting and not until the concrete has thoroughly 
set. Planks for trucking shall be so arranged as to 
come over supports. 

MATERIALS 

The materials composing the concrete or plaster 
shall consist of: 

(a) Portland Cement which has been care- 

fully tested and found to satisfactorily 
meet the requirements of the Speci- 
fications of the American Society for 
Testing Materials. 

(b) Sand which is practically free from or- 

ganic matter and uniformly graded in 
size from coarse to fine. 

(c) Broken Stone or Gravel which is good, 

hard, dense stone — clean and of such 
size as to pass through a half-inch ring. 

(d) Hydrated Lime which is uniform in 

quality and perfectly hydrated. 



APPLICATION 

Cover the Hy-Rib sheets with a concrete made up 
as follows: 

Portland Cement 1 part 

Sand 2 parts 

Broken Stone 4 parts 

The surface shall be floated smooth to receive a 
standard roofing applied as directed by manu- 
facturers. When the concrete has set sufficiently, 
plaster the under s ; de to a thickness of Y% to yi inch 
with the following mixture: 

Portland Cement 1 part 

Sand 3 parts 

Lime Paste i^q part 

The cement and hydrated lime, after being 
thoroughly mixed dry to uniform color, shall be 
added to the dry sand and the whole manipulated 
until evenly mixed. Add water to secure proper 
working consistency and sufficient long cow hair to 
key. The mortar shall be applied within 30 
minutes from time of mixing. 

PROTECTION 

The concrete work shall be thoroughly protected 
from too rapid drying and the direct rays of the sun 
by means of damp burlap or canvas, or by sprink- 
ling. The concrete slab must be kept thoroughly 
moist in this way for at least two days after placing. 

EXPANSION RODS 

Where the width of the building is over 200 feet 
in a direction at right angles to the main ribs of the 
Hy-Rib place -^ or l A inch round rods, spaced 
30 inches apart, on top of the high ribs and at right 
angles to them. 

SPECIFICATIONS FOR ARCHED 
FLOORS 

Specifications for arched floors are the same 
as above except as indicated in following para- 
graph: 

Where curved sheets of Hy-Rib are used for 
reinforcement of concrete arches it is not necessary 
to interlock the sheets along the sides, but side ribs 
shall be thoroughly wired together. Otherwise 
splice and place Hy-Rib as provided for under Floors 
and Roofs.

HY-RIB AND METAL LATH 



EXPLANATION OF HY-RIB SLAB TABLES 

(Page 17) 

The left-hand table on Page 17 gives safe loads carried by slab after the concrete has 
thoroughly set. Safe loads include weight of slab. In floors and roofs weight of the slab 
must be deducted from the loads given to determine the safe live load. The right-hand 
tables are used to determine the load Hy-Rib will carry as centering before the concrete has 
set. 

Example: Given a 6 ft. span to carry a safe live load of 1 10 lbs. persq. ft. Use tables 
on Page 17. Opposite 2 >2 -inch slab reinforced with No. 24 15 /i6 // Hy-Rib read 152 lbs. load. 
Deduct from this load 36 lbs. (Weight of 2^-inch slab + ^-inch cement plaster underneath), 
giving safe live load of 1 16 lbs. 

In table at right opposite 2 I ^-inch slab note that No. 24 15 /i6" Hy-Rib as centering 
will not support the weight of 2^" inches of wet concrete on 6 ft. span, but will carry it on a 
span as great as 3 ' 4". Therefore, use one temporary line of shoring down the center of the 
span. This shoring is removed after concrete has set.

WALLS AND SIDINGS 

For specifications and details for walls of industrial buildings, see Pages 25 to 27. 

For descriptions and details for stucco on wood studs for residences, etc., see Pages 28 to 39. 

For overcoating old buildings, see Pages 36-37. 

Monolithic concrete walls, costing one-half the price of brick, are built of 
Hy-Rib Metal Lath plastered with cement. Walls are only 2" thick, and thus add 
12 to 20 inches to the floor space on the interior as compared with brick or masonry 
walls. These walls have great strength and rigidity and are built without forms. 

Hy-Rib concrete is ideal for sidings and curtain walls of industrial buildings, factories, 
power plants, warehouses, car barns, etc. Such a wall is much less expensive than other 
types of permanent construction, and much more economical than old-style constructions 
which rust, decay and require constant maintenance. 

For stucco residences, garages, stores and all types of buildings, Hy-Rib Metal Lath 
furnishes ideal reinforcement. Studs to carry the weight of floors and roof are provided, the 
Hy-Rib Lath is attached directly to them and the cement plaster applied. The extreme 
stiffness of Hy-Rib permits wide spacing of the supporting members. For detailed in- 
formation on stucco with wood studs, see Pages 28 to 39. 

Hollow walls are readily obtained by applying Hy-Rib Lath and plastering it on the 
interior. A substantial air space for insulation is thus secured between the outer and inner 
wall. No furring is necessary, as would be required for ordinary brick or masonry. The 
air space makes a building that is easy to heat in winter and one that keeps cool in summer. 

An old-style building with wooden sidings can be transformed into a modern stucco 
structure, by applying Hy-Rib Lath and plastering with cement — the ribs of Hy-Rib furnish 
the necessary furring. See Pages 36 and 37. 

The Hy-Rib Laths tyi" and 1-A) are most generally used in walls, sidings and stucco — 
but for wider spacings of supports the deeper Hy-Ribs are recommended and for closer 
spacings lighter laths are suitable. See table, Page 27.

Bureau of Standards Investigates Stucco 

An extensive practical investigation is being conducted by the Bureau of Standards, 
of the United States Government on the permanency of stucco as applied to various bases 
and with various mixtures. A test structure 200 ft. long, 26 ft. wide and two stories high was 
divided into panels 10 x 15 ft. Metal lath was used in 19 panels, while the remaining 37 
panels were of wood lath, plaster board, terra cotta tile, brick, monolithic concrete or gypsum 
block. Various mixtures of stucco were used. 

Stucco was applied by a practical plasterer in the fall of 1915. Bulletin No. 70 of the 
Bureau of Standards reports conditions up to December 9, 1916. Of the 56 panels, only one 
— No. 15 — has received a rating of "excellent" in all inspections. This panel is of *ribbed 
metal lath on metal furring attached directly to studs with lath back plastered between 
studs; stucco mixture (parts by weight), 1 cement, 0.1 high magnesian hydrated lime, 3 sand. 

Summarizing the Report on Structural Condition in Bulletin No. 70, and considering 
percentage of panels rated "Fair" or better: 

(1) Metal Lath attached to studs without sheathing and back-plastered 
has a full 100% rating. 

(2) Metal Lath of all types of construction has a higher rating than all 
other materials, except brick and monolithic concrete, which are not com- 
parable owing to much greater cost. 

(3) A metal lath panel is the only one which has received a rating of 
"Excellent" in all inspection. 

(4) Back-plastered metal lath attached to studs without sheathing 
shows better results than where wood sheathing is used. 

In general, the investigation to date has proven that stucco on metal lath stands in 
the first rank of building methods. 

Bulletin No. 70, Bureau of Standards, may be procured from Supt. of Document. 1 ;, Government PrintingOffice, Washington, D.C., at 15 
cents. Digest of Bulletin No. 70 is furnished Free by Associated Metal Lath Manufacturers, Cleveland, Ohio.

HY-RIB PUNCH 

Length of Handles, 30 inches 

The Hy-Rib Punch has two uses: 
1st. For fastening Hy-Rib sheets together by merely clamping the interlocked ribs, doing away with all wiring. 
2nd. For punching holes through the ribs when Hy-Rib is attached to structural steel with plate clips, as shown in above 
illustration. The edge of the punch is lined up with the edge of the plate clip which is seen through the Hy-Rib mesh. The small 
point of the punch engages the hole in the clip and a wire or nail slipped through the hole rigidly fastens the Hy-Rib to the steel 
work. On roofs the use of the punch is similar; the operator can stand erect while working. 



PLATE CLIPS FOR ATTACHING HY-RIB TO STRUCTURAL STEEL 

(Patented) 

Thesejclips are made of spring steel and when driven on to the flange of the steel work, bite into the steel, gripping it like the 
jaws of a vise. A simple, rigid, and inexpensive method of attaching Hy-Rib to structural steel. Plate Clips should be located at 
the interlocking side splice between sheets. See Hy-Rib Punch above.

Specifications for Hy-Rib Walls and Sidings 



*REINFORCING STEEL 

Provide Hy-Rib, Type , Gauge , for 

all walls and sidings. 

Interlock all adjoining sheets of Hy-Rib at sides 
and ends. Sheets shall be securely fastened to- 
gether every 24 inches along the sides and at every 
rib at the ends by wiring or by clinching of the 
lapped ribs with special punch. Where end splices 
occur between supports, splices in adjacent rows 
must be at least 2 feet apart. Allow a lap of 2 
inches where splices occur over supports, otherwise 
8 inches. 

Hy-Rib shall be rigidly attached to steel framing 
by means of clips or strong galvanized wire, and to 
wood framing by staples or nails. Such attach- 
ments shall be located at the interlocking side 
splices between sheets and shall occur at least 
every 8 inches. Where Hy-Rib is attached to 
structural steel with plate clips, place lath side 
against the steel ; where attached to wood supports, 
place lath side away from the wood. 

MATERIALS 

The materials composing the plaster shall con- 
sist of: 

(a) Portland Cement which has been carefully 

tested and found to satisfactorily meet the 
requirements of the Specifications of the 
American Society for Testing Materials. 

(b) Sand which is practically free from organic 

matter and uniformly graded in size from 
coarse to fine. 

(c) Truscon Waterproofing Paste, Concentrated, 

as manufactured by The Truscon Labora- 
tories. 

(d) Hydrated Lime which is uniform in quality 

and perfectly hydrated. 

APPLICATION 

The plaster for the inside wall and for the first 
coat of outside wall shall be made up as follows : 

Portland Cement 1 part 

Sand 3 parts 

Lime Paste 1/j.o P art 

The cement and hydrated lime, after being 
thoroughly mixed dry to uniform color, shall be 
added to the dry sand and the whole manipulated 
until evenly mixed. Add water to secure proper 
working consistency. The mortar shall then be 
thoroughly worked until perfectly homogeneous. 
This composition shall only be made up in lots that 
can be immediately applied, and any material that 
has been mixed with water longer than 30 minutes 
before applying shall be rejected. 



PLASTERING OF WALLS 

Plastering on the Hy-Rib may be started either on 
the exterior or the interior, beginning at the bottom 
of the wall. Plaster surfaces to receive additional 
coats shall be "scratched," while still wet, to form 
a key for the next coat. The first coat of plaster 
applied shall be of the mixture above specified with 
the addition of cowhair or approved fibre for key. 
All other plaster coats shall be of the above mixture 
without cowhair or fibre, except that in the last 
outside coat the hydrated lime shall be omitted and 
Truscon Waterproofing Paste, Concentrated, shall be 
added to the mixing water, in the proportions of one 
part paste to 1 8 parts of water. The waterproofed 
finish coat shall be at least yi" thick, and shall be 
free from any porous imperfections. The interior 
finish coat shall be troweled to a smooth finish. 

The thickness of the plaster coat on the exterior 
shall be at least 1 yi", measured from the face of the 
lath. The thickness of the plaster on the interior 
shall be at least yi " measured from the face of the 
lath. The total thickness of the wall shall be at 
least 1 34". 

PROTECTION 

Thoroughly protect the finished work from too 
rapid drying and the direct rays of the sun by means 
of damp canvas or sprinkling. The finished work 
must be kept thoroughly mcist in this way for at 
least two days after plastering. 

EXPANSION RODS 

In walls and sidings where it is found necessary 
to run the main ribs of the Hy-Rib vertically, place 
^ or yi inch rods, spaced 30 inches apart, at right 
angles to the ribs.

STUCCO RESIDENCES AND SIMILAR BUILDINGS 

BEAUTY — The stucco house has a distinctive beauty which makes it attractive and 
desired everywhere. The absence of fire danger and upkeep expense adds a permanent 
satisfaction which increases as the years go by. 

ECONOMY — The cost of stucco construction is exceptionally low when applied to Hy- 
Rib Metal Lath, as shown in accompanying details. In fact, the cost is barely more than 
wood sheathing and clapboard sidings, which are less desirable because of the fire risk and the 
continual painting expense. Stucco on metal lath costs less than other types of perma- 
nent construction, and is more desirable than most of them. 

U. S. BUREAU OF STANDARDS— Test panels made by the United States Bureau of 
Standards on various bases for stucco (including metal lath, wood lath, plaster board, terra 
cotta tile, brick, concrete and gypsum block) show an exceptionally high standard of 
efficiency for metal lath. A panel of back-plastered Metal Lath (the type recommended 
in this pamphlet) was the only one of all tested to receive a rating of "Excellent" in all 
inspections. See page 21 for further information on these tests. 

FIRE RESISTANCE — The fire resistance of cement stucco on metal lath has been 
demonstrated in many actual fires, and in severe fire tests by official building bureaus. 
There is no question that this construction will withstand intense fires. When used with 
wood studs on exteriors it will prevent the spread of conflagrations, as the fire could be 
extinguished long before the flames had time to reach the wood studding. 

LOCAL MATERIALS — The materials to build a stucco house are easily available, as 
practically all of them are obtained locally. Sand, the principal material, is found in all 
localities; cement is stocked generally, as is also metal lath. Stucco on metal lath is the 
most rapidly erected type of permanent construction, owing to its extreme simplicity and 
the small amount of materials to be handled. 

INSULATION — Because of the air-tightness of the monolithic concrete wall and the 
the ample air space in the wall, Hy-Rib stucco houses provide exceptional insulation against 
outside weather conditions. Such houses keep ccol in the summer and are easy to heat in 
the winter; are absolutely protected against water and dampness.

How to Build a Hy-Rib Stucco House 

WHY HY-RIB LATH? — No furring strips are necessary with Hy-Rib Lath, as the 
ribs keep the lath surface away from the wood. The ribs also give exceptional stiffness so 
that studs can be readily spaced 24" centers, as contrasted with 12 to 16 inches for other 
constructions. The mesh of the Hy-Rib Lath provides a perfect key for the plaster and 
the straight, rigid surface makes an ideal surface to work upon. The interlocking ribs 
along sides of sheets avoid waste of lath in laps. 

The complete specifications on following pages and the accompanying details give full 
information on how to build stucco residences. Two types of wall construction are shown. 
Type A, consisting of Hy-Rib Lath attached directly to the studs and back-plastered, is the 
construction which we strongly recommend because of its superior behavior in tests, and its 
qualities of economy, simplicity and permanence. Type B construction, consisting of stud- 
ding with wood sheathing and waterproofing, to which the metal lath and stucco is applied, 
has, however, been successfully used in great numbers of excellent residences. 

Referring to the back-plastered metal lath (type A), the construction is very simple. 
Substantial wood framing, such as required for any good construction, is erected with 2" 
x 4" studs spaced 16" to 24" and braced with bridging between floors. The outer face of 
studs and an inch back on sides are coated with asphalt or creosote paint. The Y%" Hy-Rib 
Lath with ribs horizontal and lath surface away from studs is stapled to the studs and plas-

HY-RIB AND METAL LATH 



tered and back-plastered, all as covered by specifications which follow. Use Truscon 
Waterproofing Paste, Concentrated, in the mixing water of the last coat. 

Thus is secured a monolithic reinforced concrete wall more rigid and weathertight than 
matched sheathing and lap siding. It is a permanent, fire-resisting wall and requires no 
expense for painting or upkeep. 

Additional insulation in the wall is provided by fastening heavy waterproofing to the 
inside face of the studs, nailing $4" furring strips on the studs and applying lath and plaster. 
Thus a double air space is provided in the wall. This extra insulation, however, can 
ordinarily be omitted, in which case the lath is attached directly to the studs and plastered. 

In selecting the lath for back-plastered construction (type A), we usually recommend yi" 
Hy-Rib Lath for the exterior and 1-A Hy-Rib Lath for the interior. For stucco over sheath- 
ing, either 1-A Hy-Rib Lath or y&" Hy-Rib Lath give very excellent results. Other types 
of lath such as Standard Rib Lath or Diamond Lath also are satisfactory, but no lath weigh- 
ing less than 3.4 lbs. per square yard should be used. We ordinarily do not advise the use 
of the deeper Hy-Ribs ( 1{ H.6 ", 1 %6 ", or 1 y 2 ") for stucco houses, as stud spacings are usually 
moderate and do not call for the heavier reinforcement. 



A Fire Resisting Crackless Interior 

By all means, metal lath should be used throughout the interior for walls and ceilings 
because of its all-around permanence and economy. Metal lath reinforces the plaster, 
preventing the appearance of cracks and stopping the falling of plaster, thus saving greatly 
in the expense of repairs and re-decoration. Metal lath is permanent, fireproof and vermin- 
proof. Metal lath prevents streaking of plastered walls and ceilings. 

Under all circumstances, metal lath should be used for all ceilings and around corners, 
under granolithic, tile or terrazo finish, and throughout in bathrooms, kitchens and vestibules. 

Studding is set up for the interior the same as for ordinary types of frame construction, 
and the metal lath applied to it. Hy-Rib Metal Lath presents paiticular advantages, as its 
great stiffness permits wider spacing of studs, thus saving in the cost of studding and erecting 
it. The excellent key and stiffness save plaster and assure speedy work. 

NON-BEARING PARTITIONS — In the case of interior walls and partitions which do 
not carry any loads, we recommend the use of solid plastered partitions, consisting of %" 
Hy-Rib Metal Lath attached to small steel channels, spaced 24" to 36" centers. The 
metal lath is plastered on both sides to a total thickness of about \%". Such a partition is 
extremely rigid, fire-resisting and soundproof. Being less than 2" thick, it adds 4 inches to 
the size of the room at each partition. It is economical in cost and quickly erected. See 
complete details, specifications, etc., for these partitions, pages 42 to 44.

Specifications for Stucco on Metal Lath 

Adapted from the Standard Specifications of the Associated Metal Lath Manufacturers, in 
harmony with practice recommended by the Portland Cement Association, and in conference with 
representatives of the United States Bureau of Standards. 

In these specifications, the paragraphs marked "Type A 11 apply only to wall construction 
consisting of wood studs to which the Hy-Rib Metal Lath is directly applied and back-plastered 
without the use of sheathing boards. The paragraphs marked "Type B" apply to construction 
consisting of wood studs with wood sheathing upon which the metal lath is applied and plastered. 
All other paragraphs apply to both types of construction. 



MATERIALS 

1. CEMENT — The cement shall meet the re- 
quirements of the Standard Specifications for 
Portland Cement of the American Society for 
Testing Materials. 

2. FINE AGGREGATE— Fine aggregate shall 
consist of sand, or screenings from crushed stone 
or crushed gravel. It shall be well graded from 
fine to coarse particles, passing when dry a screen 
having eight (8) meshes to the lineal inch and should 
be clean and free from organic or other objectionable 
foreign matter. 

3. LIME — Only hydrated lime of a standard 
brand shall be used. This eliminates the possi- 
bility of unslaked lime particles appearing in the 
mixture. 

NOTE: If added dry, the lime should be first 
mixed with the cement and this mixture screened to 
make sure that no lumps get into the mortar. Or 
the lime may first be put in water, forming a milky 
liquid (which liquid must be free from lumps), and 
then added to the mortar as it is mixed. 

4. HAIR OR FIBRE— There shall be used only 
first quality long cow hair, free from foreign matter, 
or a long cocoanut fibre well combed out. 

5. COLORING MATTER — Only mineral 
colors shall be used, but no coloring matter which is 
affected by lime, Portland Cement or the elements 
is permissible. 

6. WATER — Water shall be clean, free from 
oil, strong alkalies or vegetable matter. 

7. MIXING — The ingredients of the mortar 
shall be thoroughly mixed to a uniform color, 
sufficient water added to obtain the desired con- 
sistency and the mixing shall continue until the 
cement and lime are uniformly distributed and the 
mass is uniform in color and homogeneous. 

The hair or fibre shall be added during the process 
of wet mixing. 

8. MEASURING PROPORTIONS— Methods 
of measurements of the proportions of the various 
ingredients including the water shall be used which 
will secure separate uniform measurements at all 
times. A sack of cement (94 lbs. net) is assumed to 
contain 1 cubic foot. Hydrated lime shall be 
assumed to weigh 40 lbs. per cubic foot. (An8-quart 
pail holds approximately 10 lbs.V 

9. QUANTITY— There shall not be mixed at 
one time more mortar than will be used within one 



hour. Mortar which has begun to stiffen or take 
on its initial set shall not be used. 

10. MIXING — If hand mixed, the mixing shall 
be done in a clean water-tight box and the materials 
shall be turned until they are homogeneous in 
appearance and color. If machine mixed, a batch 
mixer suitable for mortar should be used and the 
mixing continued for at least one minute. 

11. CONSISTENCY— The materials shall be 
mixed so as to provide sufficient water to insure a 
proper binding and a dense mortar free from voids. 

12. RETEMPERING — Retempering mortar, 
i. e., remixing with water after it has partially set, 
shall not be allowed. 

STRUCTURE 

13. FRAMING— Studs shall be run from 
foundation to rafters without any intervening 
horizontal grain in the wood. These studs shall be 
tied together just below the floor joists with l"x6" 
boards which will be let into the studs on their inner 
side, so as to be flush and securely nailed to them. 
These boards will also act as sills for the floor joists, 
which, in addition, will be securely spiked to the 
side of the studs. 

14. BRACING— The frame of the building 
shall be so rigidly constructed and braced as to 
avoid cracking the stucco. 

"Type A": At least once between each two 
floors, brace between the studding with 2" x 3" 
bridging, or pieces of 2" x 4" on edge, keeping the 
bracing back at least one-half (}4) inch from the 
outer faces of the stud. 

"Tyoe B" : Bracing may be omitted, as the 
sheathing boards act as bracmg. 

15. SHEATHING— "Type A": The lath is to 
be fastened direct to the studding and back 
plastered, and no sheathing boards are to be used. 
The ribs on Hy-Rib Lath provide the necessary 
furring. 

"Type B" : Sheathing boards shall be not less than 
6 inches or more than 8 inches wide, dressed on one 
or both sides to a uniform thickness of T/&" ■ They 
shall be laid horizontally across the wall studs and 
fastened with not less than 2 8d nails at each stud. 

16. WATERPROOFING BEHIND STUCCO 
(This inside waterproofing is optional.) 

"Type A" : The outer face of the stud and for one 
inch back of the face on each side where the plaster

may come in contact with them, shall he thoroughly 
waterproofed with creosote or asphalt. 

"Type B" : Over the sheathing boards shall be 
laid, in horizontal layers beginning at the bottom, 
a substantial paper, well impregnated and thorough- 
ly waterproofed with tar or asphalt. The bottom 
strips shall lap oxer the base board at the bottom 
of the wall, and each strip shall lap the one below 
at least 2 inches. The paper shall lap the flash- 
ings at all openings. When required, the lower 
horizontal edge of each strip shall be cemented 
with hot or liquid tar or asphalt compound to the 
strip below and to the grounds of flashings at all 
openings. All tacking shall be within 2 inches of 
the top horizontal edge, where tacks will be covered 
by the lap of the strip above. 

17. FURRING— "Type A": Furring strips 
are unnecessary where fi" Hy-Rib Lath, 1-A Hy- 
Rib Lath or Rib Lath are used. These metal laths 
are applied directly to the studs and sufficient 
furring away from the studs is provided by the ribs 
and the mesh. 

"Type B" : Where Y%" Hy-Rib Lath or any of 
the deeper Hy-Ribs are used, no furring strips are 
required, the metal lath being applied directly to 
the wood sheathing with the ribs extending hori- 
zontally. With other types of Truscon laths, 
galvanized or painted metal furring strips shall 
be fastened over the sheathing paper and directly 
along the line of the studs, using \ l /i" x 14-gauge 
staples (galvanized or painted preferred) placed 
12" apart. The same depth of furring shall be 
adhered to around curved surfaces and furring 
strips shall be placed not less than 1 1 / 2 " or more than 
4 " on each side of and above and below all openings. 

18. PREPARATION OF ORIGINAL SUR- 
FACE — All roof gutters shall be fixed and down- 
spout hangers and all other fixed supports and 
fasteners shall be put up before the plastering is 
done, so there will be no break made in the plaster- 
ing where they are permanently fixed. 

Wall copings, balustrade rails, chimney caps, 
cornices, etc., shall be built of concrete, stone, tile, 
or metal, with ample overhang drip groove or lip 
and water-tight joints to keep water from behind 
the plaster. 

If wood sills are used, they should project well 
from the face of the plaster and have ample drip 
groove or lip. 

Metal lath shall be stopped far enough above the 
level of the ground to be free from ground moisture. 

Care should be taken to provide for placing all 
trim the proper distance from the studding or furr- 
ing to show its right projection after the plaster is on. 

19. METAL LATH— Metal Lath shall be 
galvanized or painted, and weigh not less than 3.4 
pounds to the square yard. The metal lath used 
shall be a product of the Truscon Steel Co. 

20. APPLICATION OF LATH— Apply the 
Hy-Rib Metal Lath with the ribs extending hori- 



zontally and lath surface away from the studs, 
rigidly attaching it with staples (galvanized or 
painted preferred), stapling over each rib of the Y%" 
Hy-Rib Lath and in no case over 8" apart. Inter- 
lock the sheets of Hy-Rib Metal Lath along the ribs 
at the sides and at the ends, fastening together 
where necessary with No. 18 gauge wire to secure 
continuous reinforcement and flat surface for 
plastering. 

21. CORNERS— There shall be 6" strips of 
metal lath (Use Kornerite), placed around the 
corner and stapled over the lath or the sheets of 
metal lath shall be bent at right angles around the 
corners, a distance of at least 3 inches and stapled 
down as applied. 

22. INSULATION— (The adding of the insula- 
tion is optional). "Type A": After the Metal 
Lath on the outside has been back-plastered, 
additional air space may be provided by applying 
heavy building paper, quilting, felt or other suitable 
insulations on the inner face of the studs, fastening 
it to the studs by nailing Y" wood furring strips to 
the studs as indicated in details. Insulating paper 
may be fastened to studs before attaching furring 
strips if preferred. The lath for the interior 
plastering can then be applied to the furring strips, 
thus providing additional air space between the 
interior plaster and insulating material. 

"Type B" : When building felt or other insulat- 
ing material is to be used, it shall be applied to the 
sheathing boards under the waterproofing behind 
stucco. 

MORTAR COAT 

23. PLASTER — The first coat shall be mixed 
in the proportion of not more than three (3) cubic 
feet of sand to one (1) sack of cement, and ten (10) 
pounds of hydrated lime. Hair or fibre should be 
added in sufficient quantity to bond the mortar. 

The second coat shall be mixed in the proportion 
of not more than three (3) cubic feet of sand to one 
( 1 ) sack of cement, and if hydrated lime is used, not 
more than ten (10) pounds to one (1) sack of 
cement. 

For third coat the proportion of sand to cement 
shall not be less than three (3) cubic feet of sand to 
one (1) sack of cement. Hydrated lime should be 
omitted and Truscon Waterproofing Paste, Con- 
centrated, added to the mixing water in propor- 
tions of 1 part paste to 18 parts water. 

24. APPLICATION— The plastering should be 
carried on continuously in one general direction, 
without allowing the plaster to dry at the edge. If 
it is impossible to work the full width of the wall at 
one time, the joint should be at some natural 
division of the surface, such as a window or door. 

"Type A" : The first coat shall be applied to the 
outside of the lath and pushed through sufficiently 
to give a good key. Over the face of the studs, the 
plaster shall be forced well through the lath in 
order to fill entirely the space between the lath and

the studs. The backing coat shall be applied to the 
back of the lath and shall be thoroughly troweled so 
that the lath shall be entirely covered. 

"Type B" : The first coat shall be applied to the 
lath and thoroughly pushed through against the 
inside waterproofing so as to completely imbed the 
metal of the lath on both sides. Special care shall 
be taken to fill all voids around furring strips and 
where the lath laps. 

25. BACK PLASTERING may be applied any 
time after the scratch coat has received its initial 
set. 

26. ROUGHING— Soon after applying and 
before the initial set has taken place, the surface of 
the coats which are to receive succeeding coats 
shall be roughened with a saw-toothed paddle or 
other suitable device. 

27. DAMPENING— Before applying mortar 
the surface of the preceding coat shall be wetted to 
saturation to prevent absorption of water from the 
fresh mortar. 

28. THICKNESS OF COAT— "Type A": 
The completed stucco wall including back-plaster- 
ing shall be not less than one and one half (\}4) 
inches thick. 

"Type B" : The completed stucco wall shall not 
he less than one (1) inch thick from the face of the 
lath. 

29. DRYING OUT— The final coat shall not be 
permitted to dry out rapidly and adequate pre- 
caution shall be taken, either by sprinkling fre- 
quently after the mortar has set hard enough to 
permit it or by hanging wet burlap or other material 
oxer the surface. 

30. FREEZING — Stucco should never be ap- 
plied when the temperature is below freezing. 

FINISH 

31. SMOOTH TROWELED— The finishing 
coat shall be troweled smooth with a metal trowel 
with as little rubbing as possible. 

32. STIPPLED— The finishing coat shall be 
troweled smooth with a metal trowel with as little 
rubbing as possible, and then shall be lightly patted 
with a brush of broom straw to give an even stippled 
surface. 

33. SAND FLOATED— The finishing coat, 
alter being brought to a smooth even surface, shall 
be rubbed with a circular motion of a wood float 
with the addition of a little sand to slightly roughen 
the surface. The floating shall be done when the 
mortar has partially set. 

34. SAND SPRAYED— After the finishing 
coat has been brought to an even surface it shall be 
sprayed by means of a wide, long fibre brush; a 
whisk broom does very well dipped into a creamy 
mixture of equal parts of cement and sand, mixed 
fresh every 30 minutes and kept well stirred in the 



bucket by means of the whisk broom or a paddler 
This coating shall be thrown forcibly against the 
surface to be finished. This treatment shall be 
applied while the finishing coat is still moist and 
before it has attained its final set. i. e., within 3 to 5 
hours. To obtain lighter shades, add hydrated 
lime of 5 to 1 5 per cent of the volume of the cement. 

35. SPLATTER DASH OR ROUGH CAST- 
After the finishing coat has been brought to a 
smooth even surface and before attaining final set 
it shall be uniformly coated with a mixture of one 
part cement and two parts of sand thrown forcibly 
against it to produce a rough surface of uniform 
texture when viewed from a distance of 20 feet. 
Special care shall be taken to prevent the rapid 
drying out of this finish. 

36. PEBBLE DASH— After the finishing coat 
has been brought to a smooth even surface and be- 
fore attaining initial set, clean round pebbles or 
other material as selected, not smaller than J^" or 
larger than Y' previously wetted, shall be thrown 
forcibly against the mortar so as to imbed them- 
selves in the fresh mortar. They shall be dis- 
tributed uniformly over the surface of the final coat 
and may be pushed back into the mortar with a 
clean wood trowel but no rubbing of the surface 
shall be done after the pebbles are imbedded. 

37. EXPOSED AGGREGATES— The finish 
ing coat shall be composed of an approved selected 
coarse sand, marble dust, granite dust or other 
special material, in the proportion given for finish- 
ing coats and within 24 hours after being applied 
and troweled- to an even surface shall be scrubbed 
with a stiff brush and water. In case the cement is 
too hard, a solution of one part muriatic acid in four 
parts of water by volume can be used in place of 
water. After the aggregate particles have been 
uniformly exposed by scrubbing, care shall be taken 
to remove all traces of the acid by spraying with a 
hose. 

38. MORTAR COLORS— When it is required 
that any of the above finishes shall be made with 
colored mortar, not more than 10% of the weight of 
Portland Cement shall be added to the mortar in 
the form of finely ground coloring matter. A pre- 
determined weight of color, shall be added dry to 
each batch of dry fine aggregate before the cement is 
added. The color and fine aggregate shall be mixed 
together and then the cement and lime mixed in. 
The whole shall then be thoroughly mixed dry by 
shoveling from one pile to another through a }i" 
mesh wire screen until the entire batch is of uniform 
color. Water shall then be added to bring the 
mortar to a proper plastering consistency. 

MACHINE STUCCO 

39. STUCCO may be applied by machine 
provided the results obtained are equal to those 
produced by hand work.

Wonderful transformation of forty-five year old wood frame house to modern stucco residence. %" Hy-Rib Lath was applied directly to the 
old sid.ng without the use of furring strips. David Stott Estate, 1700 E. Jefferson Ave., Detroit, Mich. John Shea, Plastering Contractor. 



"OVER-COATED" HOUSES 

An old wood frame building can be readily transformed at nominal expense into a fine 
stucco building by the use of Hy-Rib Lath. Furring strips are eliminated by the use of 
3/g" Hy-Rib Lath, which is nailed directly to the siding with the ribs running horizontally. 

The cement stucco plaster is applied directly to the Hy-Rib Lath. Materials, applica- 
t icn and finishes are the same as for specifications for stucco on the preceding pages. The 
last exterior coat should be waterproofed with Trusccn Waterproofing Paste, Ccncentrated. 

The transformation made in a house by 
overcoating is truly remarkable. The pro- 
perty is enhanced in value by much more than 
the cost of the overcoating, and is protected 
from depreciation and fire. The saving in 
painting bills alone pays handsome divi- 
dends on the investment in overcoating.

Overcoating Specifications 

(Continuation of Stucco Specifications from page J5.) 

40. A tight roof is essential. 

Where the lath is applied over the old sheathing 
or weather board, some provision must be made for 
extending the old window or door frames. Where 
•Hs" Hy-Rib Lath is used, no furring strips are re- 
quired, as these are provided by the ribs of the Hy- 
Rib Lath. Also where the old lap siding is such as 
to provide proper space for embedding lath with 
mortar, no furring strips are required. Where re- 
quired by lath and conditions, apply furring strips 
over the old sheathing. 

In case the weather boarding is removed, it is not 
necessary to provide for extending the window and 
door frames and the new stucco finish will have the 
same relations as the old weather boarding. If the 
weather boarding is in poor condition, it should be 
removed and Hy-Rib Metal Lath applied over the 
sheathing to which waterproofing has previously 
been fastened. It may be advisable also to tear off 
the sheathing, in which case brace between the studs 
and apply Hy-Rib Metal Lath. 

The application of the Hy-Rib Metal Laths and 
stucco in overcoating is the same as for "Types 
A" and "B" construction described in the speci- 
fications, pages 31 to 35.

HY-RIB STUCCO GARAGES 

The stucco garage is always attractive in appearance, harmonizing with the simplest or 
most elaborate garden setting. It costs, in the first place, but little more and in the long run 
is much more economical than the unsightly shack which is short-lived and requires continued 
expense for painting and repairs. The Hy-Rib stucco garage provides a suitable protection 
for a valuable property against the ravages of fire, time and weather. 

Suitable framework of wood, steel or concrete is provided to which the Hy-Rib Lath is 
attached and plastered as indicated in stucco house specifications. The simplest and most 
economical construction is to use 2"x4" wood studs spaced 16'' to 2.4" centers. The outside 
face of studs may be painted with creosote or asphalt as waterproofing. z /%" Hy-Rib Lath 
is stapled to the studs, with lath side away from studs, then plastered and back-plastered to a 
thickness of about V/2 inches. The outside finish coat should be waterproofed by using 
Truscon Waterproofing Paste, Concentrated, in the mixing water. Any desired finish can be 
obtained, as indicated in stucco specifications, which also see for materials and applications. 

This solid reinforced stucco wall with studs exposed in the interior provides ample pro- 
tection against the elements, but if desired the interior may be finished by lining with ceiling 
boards, lath and plaster, wall-boards, etc.

ON THE FARM 

(Catalogue, " Hy-Rib Concrete Silos and Farm Buildings" sent on request.) 

The day of the unsightly short-lived wood frame buildings is passing, and in their place 
are found modern concrete structures. The average farm is provided with no means of 
fighting fire, so that the slightest fire may cause the total loss of a large amount of property. 
Fireproof construction is a necessity in farm buildings. 

Hy-Rib and Metal Lath, owing to their simplicity and. ease of application, make it 
possible for concrete construction to be carried on by the ordinary farm mechanic. 

The sand and stone for the concrete are easily accessible in the neighborhood — the 
Portland cement is secured from local dealers. Hy-Rib is shipped in exact lengths, and, 
where desired, bent to any curve. Its uses are found in the building of houses, barns, and 
sheds of all kinds — in constructing culverts, cisterns, tanks and silos. Fences are also built 
in this way. The methods of application are as shown under the varied uses of these mate- 
rials throughout this catalog. 

We will gladly supply detailed information in regard to any particular work that 
may be contemplated.

HY-R1B AND METAL LATH 



PARTITIONS 

Partitions of plastered Hy-Rib and Metal Lath are rigid, economical, fireproof, 
soundproof and light in weight. The thorough reinforcement prevents cracking 
of plaster, saving expense in repairs and decoration. The solid partitions are less 
than 2" in thickness, thus increasing the useful floor space and the rental value of 
the property. The ribs in the Hy-Rib Lath by their stiffness permit wide spacing 
of supports and in the case of the deeper Hy-Ribs, entirely eliminate channels, thus 
saving materials, labor and time. The flat, rigid surface and perfect key provide an 
ideal base for rapid and economical plastering. 

SOLID NON-BEARING PARTITIONS 

These are of two distinct types, either of which give satisfactory results. In the one 
type, covered fully on pages 42 to 44, the partitions consist of plastered Hy-Rib Lath on 
widely spaced channels; the wide spacing saves on channels and the labor of wiring lath to 
them. In the other type, covered fully on pages 46 to 49, the deeper Hy-Ribs { 13 Aq" and 15 /i6") 
are used with the ribs extending from floor to ceiling, entirely eliminating stiffening channels 
and the expense of wiring lath to them. The choice between the two types of partitions is a 
matter of personal preference, often dependent on local costs of materials and labor. 

HOLLOW PARTITIONS 

Hollow partitions may be bearing or non-bearing, according to the strength of the studs 
used. In either case the Hy-Rib Lath is attached to the two faces of the studs ; the stiffness 
of the ribs permits wide spacing of studs, thus saving in cost of partition. Studs may be of 
wood or steel, depending on the nature of the construction. We furnish two types of hollow 
pressed steel studs (described on page 6) : non-bearing, consisting of two % " channels 
separated by spacing bars, and bearing studs, consisting of channel or H shapes provided 
with prongs for attaching the lath. (See also page 45).

New York Fire Test on Hy-Rib Partition 

[Compiled J rom official report oj Fire and \\ aler Test made at the Columbia hire Testing ■Station, New York City, upon plaster 
partition reinforced with Hy-Rib. Test conducted by Ira H. W'oolson. E. M., in co-operation with City Building Bureaus) 

Partitions were of standard size required by the 
Building Specifications, 14'b"x9'6". No. 2b 
Gauge Hy-Rib was installed in partition; plaster 
used was Rock Wall put on in two inside and two 
outside coats, the approximate total thickness of 
partition being two inches. The partition was sub- 
jected to a continuous fire for one hour, at an 
average temperature of 1700 degrees Fahr. A \}i" 
stream of water at hydrant pressure was then 
thrown against it for two and one-half minutes. 

After the application of fire and water, the final 
maximum deflection in the Hy-Rib partition was 
only )4", and partition was in excellent condition. 

As a result of the test, No. 28 Gauge Hy-Rib 
plastered two inches thick for solid partitions, or 
with two thicknesses of metal for hollow partitions, 
has been approved for use in the Borough of 
Manhattan. 

Soundproofness of Solid Hy-Rib Partitions 

A solid monolithic partition stands in the front rank in resistance to passage of sound. 
The solidity of the construction without joints or interstices affords more effective insulation 
than block construction. The following sound test made by a leading testing laboratory in 
London, England, demonstrates the soundproofness of Hy-Rib Partitions. 

To ascertain the relative resistance to the transmission of sound of three "Telephone" 
Cabinets. Size of cabinets — 3 feet x 3 feet x b feet b inches high. 

Cabinet A. (VV. 2789.) Built with cement and Breeze partition blocks. 3 feet x 
12 inches, 2 inches thick, joints made with cement mortar, 1-3. 

Cabinet B. (VV. 2790.) Built with plaster partition blocks. 3 feet x 12 inches, 
2 inches thick, joints made with cement mortar, 1-3. 

Cabinet C. (VV. 2791.) Built with Hy-Rib Sheet reinforcement (28 gauge) coated 
each side with cement and sand mortar (1-3), and rendered to a smooth surface inside and 
out, to a finished thickness of 2 inches. 

Under varied and repeated series of observations we find that the C. Cabinet (Hy-Rib) 
shows distinctly greater resistance to the transmission of sound than either A. or B.

Solid Partitions of Hy-Rib Lath and Channels 

Wide Spacing of Studs. 
Saving of Channels and Wiring. 
Speed and Economy of Construction. 
Perfect Key for Plaster. 

The Hy-Rib Lath is wired to the channels (usually % " * n si ze ) which extend from floor 
to ceiling, and plaster is applied to both sides. The construction is very rapidly installed, 
economical in cost and in every way highly satisfactory. The extreme stiffness of y%" 
Hy-Rib Lath, owing to the ribs, permits channel spacings of 24" to 42", thus using only one- 
half the channels required with other laths. Consider the large saving not only in the chan- 
nels but in the labor and time of attaching lath to them. The perfect key for the plaster 
prevents dropping of plaster back of the lath and the flat rigid surface presents an ideal base 
to plaster against. 

Spacings of channels for various types of lath are given in specifications below, and 
details of application on the following page. For channels, see page 6.

Hollow Non-Bearing Partitions of Hy-Rib Lath and Studs 

Non-bearing hollow partitions are only required where extraordinary insulation is 
required. For practical conditions the solid non-bearing partition meets all requirements of 
soundproofness. as sound is usually carried between rooms, through doorways or crevices or 
by the floor. The solid monolithic metal lath partitions are more effective than many hollow- 
block partitions which contain unfilled crevices through which the sound penetrates. 

For the non-bearing hollow partition we furnish Truscon Hollow Studs (see Page 6), 
consisting of two %" channels separated by spacing bars, furnished in sizes to form 4" to 8" 
thick partitions. Hy-Rib Lath has the same advantages as in solid partitions.

Hollow Partitions to Carry Loads 

Studs must be of proper strength to carry loads coming on partition, using wood or steel 
according to type of construction desired. The use of Hy-Rib Laths effects considerable 
saving by permitting wide spacing of studs as indicated in table above. 

We furnish Truscon Pressed Steel Studs in channels and H shapes and various sizes as 
indicated on Page 6. These are provided with prongs in their flanges, so that the metal 
lath is quickly attached by merely bending down the prongs over the lath.

HY-RIB AND METAL LATH 



Solid Hy-Rib Partitions without Channels or Studs 

In these solid partitions the deeper types of Hy-Rib ( 1 %e' / , 15 Ae ,f or \Yi") are used and 
the ribs extend from floor to ceiling without support. All stiffening channels and studs 
are eliminated, doing away entirely with their expense and the labor of wiring lath to 
them. Hy-Rib is a unit of lath and channels, made in a single sheet of steel. The 
partitions are rigid, fireproof, soundproof and generally satisfactory. 

The mesh provides a perfect key for the plaster without its dropping behind; the rigid 
true surface is an excellent base fcr rapid plastering. The completed partition is light in 
weight and less than 2" thick, effecting marked saving in floor space as compared with other 
types of partitions occupying 6" to 8". 

As to the choice between the two types of Hy-Rib partitions with or without channels, 
each will give equal satisfaction. While the deeper Hy-Ribs eliminate channels, they are 
necessarily heavier and more costly than the Hy-Rib Laths, so the selection between the two 
types is usually governed by local costs of delivered material and labor. 

Complete details and specifications are given in the following pages.

CEILINGS 

Cracks, streaks and falling plaster do not occur in ceilings reinforced with 
Hy-Rib and Metal Lath, saving expensive repairs and re-decoration. The extreme 
stiffness of Hy-Rib permits wide spacing of supports, saving 50% of the labor and 
time in erecting the lath. 

The straight, true surface and the exceptional rigidity of the Hy-Rib Metal Lath pre- 
vent the waste of plaster in filling out uneven spaces, and eliminate the excess plaster re- 
quired by the "bowing" of the lath under pressure. The improved form of mesh provides a 
perfect key for the plaster and prevents its dropping off. 

The Hy-Rib and Metal Lath are attached to the lines of supports, using type of lath and 
spacing of supports according to table in specifications. Note that the heavy types of 
Hy-Rib will span up to 6'0" without supports, so that the ceilings can often be attached 
directly to the under side of the beams. For joists with closer spacing, lighter types of lath 
may be used. The Hy-Rib products meet every requirement from the lightest to the heaviest. 

Suspended ceilings are ordinarily built as 
indicated on next page with main supporting 
channels and lighter channels at right angles. 
By using the heavier types of Hy-Rib the 
light channels can be eliminated, or with 
the Hy-Rib Laths these light channels 
are spaced wide distances apart; in either 
case materials, labor and time are saved. 

No plastered ceiling anywhere should be 
built without metal lath. Cracked, 
streaked and falling ceilings are the bane 
of the owner of any building, whether a 
modest cottage or a magnincient hotel. 
The slight additional first cost of metal lath 
is soon more than repaid by the saving in 
repairs and re-decoration.

HY-RIB AND METAL LATH 





Hy-Rib Lath for Furring, Ceilings and Partitions. 
Grace Hospital, Detroit, Mich. 



Various stages in overcoating frame building, showing H " Hy-Rib 

Lath before plastering, after one plaster coat and finished 

stucco. No furring required for } s " Hy-Rib Lath. 



FURRING 

All furring strips are eliminated by the use of Hy-Rib products, because of the ribs. 
For furring inside or outside of walls, Hy-Rib is nailed or stapled directly to the wall with the 
lath side outward, eliminating entirely the expense of furring strips and the labor of applying 
them. The perfect key prevents plaster dropping behind and the straight, true surface saves 
labor in plastering. 

Where an air space is necessary for insulation against dampness and temperature, either 
13 /ie' / or XYi" Hy-Rib should be used, securing in this way an air space of either 13 /i6" or 1^" 
as desired. Where the furring is only required as a key for the plaster, % " or 1 _ A Hy-Rib Lath 
is entirely ample. The various types of metal laths may also be used with furring strips, 
spaced as indicated in specifications below. 

Hy-Rib is extensively used as a furring for insulation around boilers, in cold storage plants, 
and on roofs to prevent condensation. The air space between the ribs stops the conduction 
of heat, cold and moisture. 

SPECIFICATIONS FOR FURRING 



Provide Hy-Rib, type , gauge 

for all furring. 

Hy-Rib shall be placed with the lath side away 
from wall. It shall be fastened to the wall by 



means of staples or nails, occuring every 36 inches 
along the length of each high rib, points of fastening 
being staggered in adjacent rows. Interlock all 
sheets at ends and sides and allow 1 inch end lap. 



ALTERNATE SPECIFICATIONS USING FURRING STRIPS 

Provide Hy-Rib Metal Lath, type , 

gauge Rigidly attach furring strips and 

space as indicated in accompanying table. 

Interlock adjoining sheets of Hy-Rib Lath at 
sides and ends, securely fastening sheets together 
where necessary. Attach Hy-Rib Lath to furring 
strips at least every 8 inches. Where end splices 
occur at supports a lap of 2 inches should be made ; 
otherwise 8 inches.

The curved Hy-Rib sheets are set up on edge and the plaster applied directly to the inner 
and outer surfaces. No forms of any kind are required. 15/ i6" Hy-Rib is furnished bent to 
curve by our shops. Vertical Rib Bars about 5 feet apart should be used to serve as a guide 
for the Hy-Rib sheets and to thoroughly tie the concrete work together vertically. 

Hy-Rib sheets provide in themselves a thorough interlocking splice at the ends and sides. 
Lap the sheets at least 8 inches at ends and securely fasten together each spliced rib. Splices 
in adjacent rings should be at least two feet apart. Follow specifications for Hy-Rib walls 
and sidings, page 27, for materials and application of plaster. 

It is usually difficult to plaster a solid wall to a greater thickness than 4 inches. When 
heavier solid walls are required we recommend the use of a double layer of Hy-Rib, pouring 
the concrete in between the two sheets. 

Where an air space is desired on walls of silos an inner and outer layer of Hy-Rib is used 
with our Truscon Pressed Steel Hollow Studs to separate them. The inner wall is plastered 
on both sides and the outer wall on the outside only.

CONDUITS, FLUMES AND CULVERTS 

The 15 /i6 ,/ Hy-Rib is bent to perfect curve in our shops. Simply set up the curved sheets 
on the job, and apply the concrete as a plaster. 

Absolute continuity of reinforcement is secured by the positive interlocking of the sheets 
at the sides and ends. No forms (the principal item of expense in conduit construction) 
or special field labor are required. A few reds, as shown on illustration, extending the length 
of the conduit, should be provided to keep the Hy-Rib straight in line and as an additional 
safeguard against any shrinkage and temperature cracks. Rib Bars are recommended for 
this purpose. 

Either side of Hy-Rib may be plastered first.

HY-RIB CUTTER 

For Shearing All Types of Hy-Rib. 

Where Hy-Rib must be cut to various lengths, and fitted around openings, most builders 
find it more economical to order Hy-Rib in standard lengths, and cut the sheets to the re- 
quired size on the job. 

The Hy-Rib Cutter is a portable shear for cutting Hy-Rib sheets to any desired length. 
It weighs only 85 lbs., and can be readily carried by one man from one location to another. 
In jobs of any size, the Hy-Rib Cutter pays for itself many times over. It saves time, labor 
and expense over the use of the ordinary tinsmith's tools. Many of our representatives have 
Hy-Rib Cutters which can be rented for use on small-sized jobs. 

Cutters 



Hy-Rib Cutters are furnished complete, 
ready for mounting on suitable base. The 
shear blades are detachable for sharpening. 

The Hy-Rib Cutter is designed so as to shear 
13 /i6" and 15 /i6" Hy-Rib with the same blades, 
and 13^2" Hy-Rib by merely changing the 
blades in the cutter. These two sets of blades 
are furnished with each cutter.

Hy-Rib Lath with Truscon Pressed 



TRUSCON PRESSED STEEL CONSTRUCTION 

In buildings of all types, Truscon Pressed Steel Joists and Studs with Hy-Rib Lath 
provide a permanent, fireresisting construction for floors, roofs, partitions, walls, etc. No 
forms, no centering and no special equipment are required. Merely set the Pressed Steel 
members in place and apply the plaster and concrete. 

Truscon Pressed Steel is simple to erect, economical in cost, permanent and fireproof. 
The construction is verminproof — no rats, mice, roaches, nor vermin of any kind to ruin the 
building. The metal lath prevents cracking, streaking and falling of the plaster. 

Truscon Pressed Steel has the advantage of fireproof construction, and can be eco- 
nomically used in buildings of any size. It is erected with equal safety in the coldest weather 
and is light in weight, saving greatly in the floor itself and in all supporting members. 

Truscon Pressed Steel beams may be supported by walls or by means of structural steel 
or reinforced concrete beams. Otherwise the entire interior construction may be made of 
bearing partitions formed of Pressed Steel Studs.

STEEL FLORETYLES- 




CHAIR AND 
SPACER 



STEEL FLORETYLE CONSTRUCTION 

3/g" Hy-Rib Lath is used for ceilings in connection with Steel Floretyle and Steel Flo re- 
dome construction, providing a flat ceiling and a perfect surface for plastering. 

Steel Floretyle construction consists of rows of hollow steel tile covered with a thin layer 
of concrete and separated by reinforced concrete joists. The joists, spaced approximately 
243^" centers, carry the load directly to the supports while the Floretyle acts merely as a filler, 
saving concrete and reducing dead load. The corrugated Floretyles have extreme rigidity 
in the top, especially formed corners, corrugated sides and corrugated flanges along the 
bottom edges, so as to provide great stiffness in supporting loads. 

Steel Floredomes are similar to Floretyles, except that they are only open on the under 
side, so that joists may extend on all sides of the dome, and carry the loads in two directions 
to the supports. More complete information on Floretyle and Floredome constructions is 
furnished in special literature of the Truscon Steel Co.
